More Details

Znyth™ (zinc hybrid cathode) battery technology. Titanium current collector with proprietary ceramic coating is permanently conductive, non-corrosive, and self-healing. Aqueous, near neutral pH electrolyte is non-dendritic and does not absorb CO2, eliminating carbonate clogging issues
Proprietary electrolyte additives and buffering agents enhance zinc solubility and plating to improve energy density and run-time. Hybridization of cathode chemistries and electro-active catalysts improves power density and roundtrip efficiency. Highly standardized manufacturing processes such as metal stamping and injection molding to keep manufacturing costs low. $160/kWh for the DC system. Aurora is projected to last 10,000 cycles for a 30-year calendar life. With a round trip efficiency of 75% in full depth of discharge applications.
